Indium phosphide shallow homojunction solar cells made by metalorganic chemical vapor deposition

Abstract
The fabrication of highly efficient indium phosphide solar cells is described. The cells are formed by metalorganic chemical vapor deposition. A shallow homojunction design is discussed and total area air mass zero efficiency of 17.9% is reported; air mass 1.5 efficiency is 20.4%. Electrical characterization identifying loss mechanisms is made, and areas for possible improvement are summarized.
